The role of the vestibular system during physical exercise has only been rarely analyzed by scientific investigations. An investigation was carried out with the purpose of obtaining information on vestibular regulation in rowers. The process of maintaining balance in the boat and the limiting factors were examined. Twenty beginners and 20 well-trained rowers participated in standardized vestibular tests in the laboratory as well as in the boat (single) on the water. The results suggest that several mechanisms in the physiologic field (torque of the body) are affected by training. The well-trained oarsmen showed a significant minor nystagmus frequency, and this criterion for general vestibular regulation also showed a relationship with the specific ability for maintaining balance in the boat.
